In Facebook comes always the notification "Send a birthday message!" in the messenger everytime when Facebook friends have their birthday.
There is no push message, but the icon gets the red notification sign, which is kinda anoying, because I have to check it then for new messages which I may have received.
It looks like this in a web browser:
The birthday notifications are turned of in general in my Facebook profile, but these messages are still showing up since a few weeks.
How can I switch off these notifications?
